Stop that annoying drip and save water with this simple faucet repair guide. Learn to identify the type of faucet you have and replace worn-out washers or cartridges.

Locate the shut-off valves under the sink and turn them clockwise until fully closed. Turn on the faucet to release any remaining water pressure.
Pop off the decorative cap on the handle using a flat-head screwdriver. Remove the screw underneath and carefully pull off the handle.
Use your wrench to unscrew the packing nut. Pull out the stem and inspect the washer at the bottom. If it's worn, cracked, or deformed, that's your culprit.
Take the old washer to the hardware store to find an exact match. Apply plumber's grease to the new washer and reassemble in reverse order.
Turn the water supply back on slowly. Check for leaks around the handle and spout. Congratulations — no more drip!
If the leak persists, the valve seat may need resurfacing. Consider calling a professional.
